Social Security systems contain tens of millions of lines of code written in COBOL, an archaic programming language. Safely rewriting that code would take years—DOGE wants it done in months.
I wouldn’t necessarily agree it needs to be rewritten. Hiring programmers that are willing to work in cobol would certainly be harder than other languages though, because you’ll have a much smaller candidate pool and people would be unlikely to see learning cobol as a good career investment
COBOL is the career advise you hear people give for people who want to make money but don’t want to deal with the VC clownshow. COBOL btw is only 13 years older than C and both language’s current standard dates to 2023.
It’s at its core a bog-standard procedural language, with some special builtins making it particularly suited to do mainframe stuff. Learning COBOL is no worse a career investment than learning ABAP, or any other language of the bureaucracy. Sure you’ll be a career bureaucrat but that’s up sufficiently many people’s alley, no “move fast and break things”, it’s “move slowly and keep things running”.
The language isn’t the problem with COBOL, it’s the likelihood that you will be maintaining (not adding to, but maintaining) a software system that may not have any docs and the original implementers are dead. Next, there will be nobody to verify the business rules that are specified in the code. Finally after you make a mistake about a business rule, you will be thrown under the bus.
Everything that you said is correct, except the prevalence of the career advice. I would bet most people looking for their first job out of school don’t even know COBOL is a language.
Well, the other thing about COBOL is that most people would regard it as a living death to have to deal with it as a day job.
And I’ve had interactions with offshore COBOL shops. The ones I worked with were not at all good. You’ll never get 99th-percentile coders to work in that language, unless their only motivation is money.
The attractiveness of learning it was that you could avoid boom and bus cycles of retrenchment and clowns like Elon musk. Unfortunately that isn’t true anymore so I think once the dust settles, finding people willing to specialize in tech like this is going to get real hard.
Is that true everywhere or just in the US? I know that, at least a few years ago, a bunch of banking software in the US was still in COBOL but parts of Western Europe were modernizing their banking industry. I’m probably going back to school for computer science in the fall and had been considering trying to learn COBOL in my free time, or learning more Fortran (I have actually taken a programming class with Fortran, but because it was aimed at beginners it didn’t really go in depth, but I bet it’d look good on certain resumes). It’s looking like my future is in Europe somewhere, so I’m keeping that in the back of my mind while making decisions.
I’m not enough into that industry to actually give a good estimate, here, but the amount of COBOL systems still up and running is certainly not even close to non-zero, and it’s going to stay that way for a while. From what I gather for companies moving away from COBOL is more of a “programmers are hard to find” situation, not “these systems absolutely must be replaced” one. It’s well-supported and scaled with their business, as in, in places they’re running the same 60 year old code on new mainframes because if there’s one thing that IBM mainframes are then it’s excessively backwards-compatible.
As far as the language is concerned: It’s not hard, it’s just weird, dating back from an age where people thought randomly calling things “divisions” would make businesspeople capable coders. The reason I’m not in that space isn’t because of the language but because of the type of software you write there, it’s all bookkeeping and representing business procedures, as said: Bureaucracy.
Also I’m not sure what “modernising” actually meant, there: SEPA instant payment was introduced, meaning that mainframes won’t batch up the day’s transactions and then talk to each other every night so cross-bank transfers took a day to process, now they’re doing it in ten seconds. Most banks already supported instant transfers within their own systems so they should only have had to rewrite the external interface as the rest was already up to the task.
